Abstract

Deaeration apparatus for removing entrained air from liquid paper coating and method includes a cylindrical vortex tube which has an inlet end with a vortex generator insert formed with helical flighting surrounding a solid center shaft. The flighting has an outer diameter which is proportioned to be received in the tube inlet and causes a vortex flow to the coating material. A rejects conduit is positioned in the outlet end of the vortex tube with an opening which faces the vortex generator insert and which is positioned on the axial center of the tube and spaced from the vortex generator. The entrained gas forms as bubbles on the vortex generator shaft and form a column immediately downstream of the insert so that the base of the column is at the inner end of the generator shaft and extends toward and into the rejects conduit. The very small bubbles are also carried by the mass flow of the coating toward the outlet end of the tube and into the open end of the reject conduit. The deaerated liquid flows through the tube outlet which surrounds the reject conduit. A deaeration system is disclosed which includes a housing containing a plurality of the individual vortex tubes arranged in flow parallel to each other with common inlet and outlet manifolds.
